when steping on the gas al the way the car starts to jerk like if something is letting it from not going fast at this moment the car only go

gtp grand prix 07 3.800 supercharged

When you stomp on it the supercharger kicks in, and when I say stomp may be bad choice of words..just hit the throttle pretty good. Do you hear a squeal by any chance? That would be the belt on the supercharger straining to turn it. Check the oil in supercharger. It's not spark plugs, I looked it up and it has iridium plugs good for 100,000 miles. (unless you have put that many miles on the clock) And yes, if the fuel filter is clogged, (not pump) it is just starving for fuel ..positive pressure induction really demands a good fuel pressure

thanks ill check it out .
